    摘要： A method of assembling a spring inside of a tube includes providing a coil spring and a tube having a first retaining structure at a first end of the tube. The method includes positioning a rod in the tube. The spring is positioned in the tube, and a second retaining structure is attached to the rod with the spring positioned between the first and second retaining structures. A force is applied to the spring, and the second retaining structure is fixed at a position wherein the spring provides a desired preload.

    摘要： A chair back assembly includes a back shell member comprising a laterally extending top and bottom portions and a pair of longitudinally extending side portions extending between the top and bottom portions and cooperating therewith to define an open space therebetween, a cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over the back shell member to cover at least a portion of the open space; and a back frame assembly operably supporting the back shell member and moveable between an upright position, and a reclined position, wherein the back frame assembly causes the back shell to flex in a fore-to-aft direction as the back frame assembly is moved between the upright and reclined positions independent of an external force being exerted on the back shell member.
